For those that don't know, the Volt caught on fire weeks after a crash due to a coolant leak that ended up causing a short circuit. This was partially because GM's own recommendation of draining the coolant after an accident wasn't followed.

Now, GM is adding reinforcement to all new cars as well as sensors to track coolant levels. They have also made a tamper-proof cap to prevent overflow.

These modifications will add a negligible amount of weight to the car.

Hopefully, this will also calm down the irrational fear that had overwhelmed the Volt since the fires were disclosed.
